To determine how high a tennis ball will bounce when dropped from a . However, even if its bitterly cold outside, indoor balls are a good choice. The tennis ball was then dropped from various heights; 1, 1.5 and 2 meters above a hard surface, using a meter ruler, before it was dropped onto the ground and the resulting bounce height measured. : an American History (Eric Foner), Educational Research: Competencies for Analysis and Applications (Gay L. R.; Mills Geoffrey E.; Airasian Peter W.), The Methodology of the Social Sciences (Max Weber), Biological Science (Freeman Scott; Quillin Kim; Allison Lizabeth), Campbell Biology (Jane B. Reece; Lisa A. Urry; Michael L. Cain; Steven A. Wasserman; Peter V. Minorsky), 4-3 Assignment Project Management Strategies. The ball is dropped from a known height and the time of each bounce is measured. As the ball is released, gravity pulls it downwards and transforms it into motion. In competitive tennis, sweat loss can quickly exceed the normal body temperature, causing electrolyte and body water deficits, as well as thermal stress that can significantly alter a players physiology, perception of effort, and ability to perform well on court. Line up the top of the table tennis ball with the top of the metre ruler (i.e. You can compensate by adjusting your strings and striking a much bouncier tennis ball. Answer (1 of 2): Some surfaces absorb more energy than others do. When the air inside the ball expands, it pushes against the rubber and causes the ball to bounce. Kinetic energy and ball shape. Air is pumped into the ball and causes it to bounce. Let's see if physics can explain what happens. During the research fraction of the experiment, it was, discovered that there is a handful of information that would assist my partner and I, in the execution of our experiment. According to our background research, a if different balls are bounced on different surfaces, then a rubber ball, hen a ball hits a surface, all its kinetic energy has to go somewhere. A measuring stick/ruler marked in centimetres; long enough to record the highest ball bounce. You can check the weather stats at. All rights reserved. Science Buddies Staff. Then they would be dropped from a table, and the height would be measured. The air in the ball expands and contracts as it is compressed. This means that the faster that the ball travels the larger the force of air resistance upon it. What factors affect the bounce height of a ball?

As in both cases the main form of energy is GPE it follows that the higher the ball is dropped from, the higher the ball will bounce. Five repeats were done as it was deemed that an average of the middle three was reasonably accurate. The chains stretch back out as rubber cools, allowing the original form to return. Do different kinds of balls bounce differently? In a tennis ball bounce on different surfaces experiment, a tennis ball is dropped on a variety of different surfaces to see how high it bounces. Air resistance exists but does not affect the velocity of the ball significantly. . The strength of Nadals forehand is what makes him so good on clay. There are many other great ball projects in this fun book by Madeline P. Goodstein. Hard court tennis demands a lot from your joints! Tennis balls are more likely to bounce on grass. Removing the maximum and minimum results and taking an average of the middle three results also provided more accurate results. You can also try using a hair dryer to heat the ball up. Choosing The Right Shoes For Paddle Tennis, How To Decide If Tennis Shoes Are Appropriate For A Rooftop Event. If it bounces up less than .5 meter, then it is more inelastic. This means that if a heavier ball is to be used then it will need to be dropped from higher to reach its terminal velocity. However when the ball is dropped from a relatively low height, drag 0. Ball trial 1 trail 2 trial 3 average The steel has a lot of bounce power due to its better storage of energy. The ball has reached its terminal velocity and cannot fall any faster (unless dropped in a vacuum). As there is more GPE more energy is converted into KE (The ball is going faster, KE=1/2mv. (Doherty, 1991). The surface onto which the ball is dropped upon will be kept the same. I think this is From this I am able to determine that the experiment was very accurate. As the ball falls it hits against air particles. A similar length stick, marked in 5-10cm bands of colour. This was added onto another issue we had to In this practical, students may use a variety of different balls to determine which type is most efficient. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot. Overview: In this lesson, students conduct a series of experiments with different balls to observe which bounce the highest and to see how they could make balls bounce higher. would bounce the highest on a hard, smooth concrete surface because a rubber ball With heavy topspin on high-friction surfaces, the horizontal velocity of the ball is attenuated greatly after the ball strikes the court, and the ball jumps into the air in ways that seem unnatural to players accustomed to playing only on hardtop. This would allow one to find the terminal velocity of the ball. As the ball hits the blades of grass, they bend and don't provide as much upward rebound. Keep releasing pressure and repeating the experiment until the ball no longer bounces. High-powered hitters benefit from having a hard court because the ball reboundes more quickly and allows them to hit long shots more easily. by Jonah Lehrer on September 8, 2011. he official rule book of tennis is 35 pages long. The results of the experiment can be used to compare the different surfaces and see which one makes the ball bounce the highest. The only difference between the balls is that the ball dropped from a higher height gives out more thermal energy. h1 = The distance between the bottom of the ball before it is dropped and the ground. By clicking Accept All, you consent to the use of ALL the cookies. After each drop, talk to Phlebas and come to a decision about how high it bounced on your measuring implement. This cookie is set by GDPR Cookie Consent plugin. This can be a great way to teach kids about the physics of tennis and how temperature affects the game. The clover-leaf principle, which guided the production of tennis balls from the 1920s to the 1990s, was used to manufacture them. Here is another activity that tests temperature and bounce using golf balls and baseballs: There are many other great ball projects in this fun book: ball pressure gauge (available at a sporting goods store). What affects ball bounce? Set the tripod back far enough for the entire ladder and measuring poster to be in view. Reproduction of material from this website without written permission is strictly prohibited. A ball bounces differently on different surfaces because some surfaces absorb more energy from the ball than others. A glass ball will bounce higher than a rubber ball if it doesnt break. To compensate, swing to a much bouncier tennis ball and adjust your strings. Reverse Engineering: Ball Bounce Experiment Hands-on Activity Reverse Engineering: Ball Bounce Experiment (2 Ratings) Click here to rate Quick Look Partial design process Grade Level: 4 (3 - 5) Time Required: 1 hours 45 minutes (2 or 3 class periods) Group Size: 3 Subject Areas: Students investigate balls and their bounce copyright Summary Hypothesis: if different balls are bounced on different surfaces, then a rubber ball The variation between results was obtained by taking the minimum result away from the maximum result. Gather 15 to 20 tennis balls and a measuring tape. Length of Lesson: 30 - 45 minutes. When it hits the ground, the bottom of the ball becomes flat against the floor. Masses of tennis balls range between 56.0 and 59.4 grams (2011). The Graph on page 23 shows that all of the results were very close together. Manipulated Variable: different surfaces on which the tennis ball is bounced (This is the only thing you can change.) The ball showed signs of reaching terminal velocity because the drag force began to approach the force gravity exerts upon the mass of the ball. use four meter sticks and go right the way up to four meters. Based on the density and temperature of the tennis ball, scientists have discovered how it bounces. 30% of the energy that the ball hits the floor wit is lost. During the preliminary experiment it was established that time was not an important factor that had to be taken into account when deciding how many different heights to drop the ball from and the interval between those heights. Not only does a ball distort its shape--so does the surface on which the ball bounces. As the ball flattening upon impact with the floor is not visible as it happens so quickly it would be almost impossible to measure the size of the ball on impact with the floor. This is because the ball starts with more GPE. Not Drag is a squared function of velocity and therefore as the ball drops drag increases a greater amount each second. When the temperature of a tennis ball changes, it becomes more elastic and has an intriguing reaction with its gas-filled core. Method: 1. Focus. Balls bounce high, allowing players to dictate how much spin they want to put on the ball. his the height of the balls bounce. Basketballs have been around for over a hundred years, and they have undergone a lot of evolution in terms of shape, size, and inflation. It relates to how much energy balls have, what they are made of, how they change shape and where the energy they have goes. The Cold Group (-15C) averaged 53.5 cm, the Cool Group (6C) averaged 98.5 cm, the Room Temperature Group (46C) averaged 114.5 cm, the Warm Group (100C) averaged 136.5 cm, and the Hot Group (142.5 cm) averaged 142.5 cm It was determined to be correct to my hypothesis. When the temperature is below 68 degrees, the ball will bounce less. Calculating the coefficient to restitution of ball hitting the floor: The coefficient to restitution can be found out from a graph of h1against h2. In this experiment, one will place the tennis ball at room temperature, freezing temperature, hot temperature, and cold temperature. 2. Here's what you need to do this experiment: Bouncy Balls - a least 6 identical balls; A measuring cup or mug for heating water in the microwave; Access to a freezer . Therefore the coefficient to restitution = 0.7. Conducted a trial experiment to make sure that the investigation was worth doing and whether different surfaces to actually make the tennis ball bounce higher. An alternative method would be the measuring person holding a video camera level with the approximate height that the ball reaches after bouncing and videoing the ball reach the top of its arc. These two results were excluded when averages were being calculated and therefore the average variation between results used for calculating the average was even less than 3cm. Also it shows inaccuracies in the experiment as it shows that heights were recorded that exceeded the height that the ball would have reached had it been dropped in a vacuum. The tennis balls bounce in different ways. From this it can be seen that using the average of the middle three results is more accurate than using the average of all five, as it automatically discounts most anomalies. Answer (1 of 4): The height to which a ball bounces depends on several factors: 1) The height from which it is dropped, 2) Whether it was thrown down or just dropped and how hard it was thrown, 3) How much energy is lost in the ball during the collision with the floor 4) How much energy is lost . The exact interval will be determined after the preliminary experiment, as will the number of heights that the ball will be dropped from. Does height make a difference? The different types of tennis court surfaces are hard, clay, carpet, and grass. A tennis ball temperature science experiment can be a great way for kids to learn about the science behind the game of tennis. As energy cannot be created or destroyed it follows that the energy must have come from the energy that the ball possesses. This is because the ball starts with more GPE. . We use cookies and those of third party providers to deliver the best possible web experience and to compile statistics. The height of the ball at each bounce is then calculated. Warmer balls bounce better than cold ones. Therefore the ball ends up with more GPE, , assuming g and m stay constant, results in an increase in m g h, , assuming g and m stay constant, results in a decrease in m g h, As the ball is accelerating due to gravity, at 9.81m/s. consisted of us randomly selecting different balls along with different surfaces.

The aim of the experiment my partner and I performed was to find out which Once the drag force equals the gravitational force all forces are equal and acceleration stops. This means that we can approximately calculate the amount of energy that the ball conserves as it hits the floor and therefore the height to which it will bounce for any given height in a vacuum. If you play in hot weather, your balls may bounce significantly more. In this paper, the dynamics of a bouncing ball is described for several common ball types having different bounce characteristics. The balls finish up with the same amount of energy and the only energy given out is thermal energy. Hypothesis. Few independent variables will be changed, so the investigation is easy to manage, and the data is easier to process. Aim: to find out which surface bounces a ball the highest. Most experiments investigate the effect of an independent variable on a dependent variable. Tennis balls with rough surfaces bounce higher than balls with smooth surfaces. External factors, i.e. Decide on a height you want to drop the balls from . The bounce of the ball is a major factor in the game of tennis. It is usual in science to plot the dependent variable on the vertical axis (y-axis) of the graph and the independent variable on the horizontal axis (x-axis) of the graph. that bounced the highest on the smooth concrete. In the heat, the molecules are more active, so the ball can bounce higher . stay constant, results in an increase in m g h, stay constant, results in a decrease in m g h, The surface onto which the ball is dropped will affect the height to which the ball bounces because for any two objects that collide, the properties of both determine the percentage of the kinetic energy either possesses approaching the collision that is conserved subsequent to the collision taking place (Coefficient to restitution) discounting the effects of air resistance. As CR = h2/ h1it follows the gradient of the graph change in h2/ change in h1= CR. The bouncing of a tennis ball on a tennis court surface is analysed by making several simplifying assumptions about the physics of the interaction. Use a uniform surface to drop the ball onto. Also the difference between the force of air resistance acting upon a ball travelling at 1ms, and the force of air resistance acting upon a ball travelling at 2ms, is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms, and the force of air resistance acting upon a ball travelling at 21ms, , the faster the velocity that the ball reaches. The Physics of Grass, Clay, and Cement. Each ball in a can is different in weight, diameter, and bounce. This results in faster . Which surface bounces a ball the highest? Repeat steps 1-6 with the different balls. It should be on a smooth cement surface for optimal ball bouncing. Tiles3. Therefore the results are valid. This is correct unless the ball shows signs of reaching terminal velocity. Graph 1. We then bounced the balls on the surfaces and, measured the heights. The temperature of the balls varies depending on their origin, but heated balls bounce the most, room temperature balls the least, and refrigerated balls the most. This is longer than the 5-8 ms ball bounce from a solid surface or racquet. When the ball is pulled toward the ground, gravity slows it down so that it doesn't bounce as many times. From dropping the ball we can see how high the ball will bounce to after having a loss or gain of energydue to sound or movement of the ball as it hits a hard surface. The more KE the ball leaves the floor with the longer it takes to stop due to the force of gravity and return back to the floor again. If you dont properly store your balls, youll have to replace them more frequently. - Pencil x The higher the height from which the ball was dropped from, the higher the height to which it bounced. The cookie is used to store the user consent for the cookies in the category "Performance". Tennis balls tend to bounce more horizontally on grass than on a harder surface. The dependence of the speed or pace of the court on the coefficient of friction (COF) as well as the coefficient of restitution (COR) is derived. The more KE that the ball possessed as it hit the floor, the more that was transferred into elastic potential energy and back into KE. Two different types of balls, Penn Championship and Non-Championship will be compared. This is why you should have seen that when you bounced the basketball on a relatively hard surface it bounced higher (it lost less energy) compared with when it was bounced on a softer surface . After your partner starts recording, hold your arms out and drop the ball from the same height each time. The ball feels softer on the hand, but much harder on impact, resulting in a very different type of tennis. Averages are more reliable than using one result as they take into account variation between results. The maximum and minimum results were included when working out the variation between results however, seeing as the maximum and minimum results were produced by the experiment and are therefore part of the variation between results produced by the experiment. In our Measuring the height to which the ball bounced on subsequent bounces would be interesting, seeing if h, Less than half the price of our monthly plan. I plan to collect at least ten results as this will make the conclusion and graph I am able to draw from the experiment more accurate than if I had less results than ten. At 2ft, the basketball bounced 15 inches, the tennis ball bounced 12 inches, and the golf. This is due to an inelasticity in the energy lost when the ball collides with the ground, as well as the fact that the ball bounces every time it is hit. found that different surfaces absorb different amounts of energy, and the less Also the difference between the force of air resistance acting upon a ball travelling at 1ms-1 and the force of air resistance acting upon a ball travelling at 2ms-1 is far smaller than the difference between the force of air resistance acting upon a ball travelling at 20ms-1 and the force of air resistance acting upon a ball travelling at 21ms-1. Overall, our experiment taught us that harder With this information, we No balls will be allowed to roll around upon the floor creating possible tripping hazards, Safety spectacles will be worn at all times, Clamp stand, meter rule 2, table tennis ball, desk. This is because the higher the starting height of the ball, the higher the ball's potential energy. This is because it is easiest as the figure read of the meter rule is the result. - tennis ball x Analytical cookies are used to understand how visitors interact with the website.
